Description

Technical Field

[0001] The utility model relates to the technical field of purifiers, in particular to an air purifier with convenient filter element replacement. Background Art

[0002] Air purifier, also known as air cleaner or air refresher, refers to a product that can absorb, decompose or transform various air pollutants and effectively improve the cleanliness of the air. It is mainly divided into household, commercial, industrial and building types.

[0003] Existing air purifiers are mainly composed of a shell, a filter device, a fan and a control system. The working principle of an air purifier is mainly to filter, adsorb, kill and settle pollutants in the air through components such as air filters, thereby achieving the purpose of purifying the air.

[0004] When replacing the filter element of an existing air purifier, it is necessary to disassemble the outer shell that is fastened with clips or fixed with screws. During the disassembly process, the clips are easily broken or the screws are lost or stripped, which affects the secondary assembly form of the outer shell. At the same time, when replacing the filter element, it is inconvenient to take out and detach the filter element, which is inconvenient to operate. Therefore, in order to solve the above problems, an air purifier with convenient filter element replacement is proposed. Utility Model Content
